cordova-plugin-contacts - 联系人挑选应用程序崩溃android M

我使用cordova-plugin-contacts从联系人中选择联系人。应用程序在Android 5（棒棒糖）和以前的版本上工作正常。但是当我选择一个联系人时，Android 6（Marshmallow）应用崩溃。cordova-plugin-contacts - 联系人挑选应用程序崩溃android M

这里是我的javascript：

navigator.contacts.pickContact(function(contact){ 
      $scope.contact.name=contact.displayName; 
      if(contact.phoneNumbers) { 
       msgToastService.toastMsgAlert('Number picked: ' + contact.phoneNumbers,'Contact',"SC"); 
      } else { 
       msgToastService.toastMsgAlert('Choose Valid Mobile Number!','Contact',"SC"); 
      } 
      $scope.$apply(); 
     },function(err){ 
     });

作为异常说，有一个ContactManager.java:246中的NullPointerException。所以我检查了插件代码，发现ContactManager的对象被重新创建，onActivityResult被调用。在那里为ContactManager的所有成员变量变为null。

我找不到为什么会发生这种情况。请查看插件代码的cordova-plugin-contacts git repository。

我科尔多瓦版本：5.3.1

Android SDK中：棉花糖（6）API级别-23

请让我知道如果你想要的任何详细信息。提前致谢。

这可能是由于在棉花糖上实施的权限，您需要在操作之前检查权限。它叫做'RuntimePermission' –

你使用的是哪个版本的插件？ – Uri

这正是因为运动员许可的棉花糖的变化。 @Murtaza Khursheed Hussain是对的

以下是修复方法：在访问移动设备的任何模块之前，您必须确保用户允许该权限。在你的情况下，它的接触，这也适用于其他情况如位置，文件存储，摄像头，传感器等

可以使用cordova.plugins.diagnostic插件要求运行时权限

安装插件（cordova.plugins.diagnostic）： $ cordova plugin add cordova.plugins.diagnostic

尝试包装你的代码如下：

cordova.plugins.diagnostic.getPermissionAuthorizationStatus(function(status){ 
    //Check for contact permission status 
    if(cordova.plugins.diagnostic.runtimePermissionStatus.GRANTED !== status){ 
     //request for permission at runtime 
     cordova.plugins.diagnostic.requestRuntimePermission(function(statusAfterRequest){ 
     if(cordova.plugins.diagnostic.runtimePermissionStatus.GRANTED === statusAfterRequest){ 
      //Your code here.. 
      //navigator.contacts.pickContact(.... 
     } 
     }, function(error){ 
     console.error("error while requesting permission: "+error); 
     },); 
    } 

    }, function(error){ 
     console.error("The following error occurred: "+error); 
    }, cordova.plugins.diagnostic.runtimePermission.READ_CONTACTS);

下面是详细信息插件页面。 cordova.plugins.diagnostic

希望它有帮助！ :) 有一个美好的一天
